Care
Pictichromis diadema is a hardy species that adapts well to life in captivity. They require an aquarium with plenty of rockwork and hiding places to feel secure. Although they are generally peaceful, they can become territorial, especially towards conspecifics or similar-looking fish. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, will help maintain their coloration and health.
Reproduction
In the wild, Diadem Dottybacks are protogynous hermaphrodites, meaning they are born female and have the ability to change to male if no male is present. In the aquarium, breeding can be achieved with a well-established pair. The male will guard the eggs until they hatch, which typically occurs after several days.
Habitat
Pictichromis diadema is native to the Indo-Pacific region, where it inhabits coral-rich areas and reef slopes. They are often found at depths where light is sufficient to support the coral ecosystems they associate with.
